The production of a hole in a mechanical component is usually done by using a drill. Although drilling a hole appears to be a simple operation, the accurate drilling of a hole of the right size at the right location, can be difficult. A large number of tools and machines have been designed for the drilling of holes economically, accurately, and quickly,

A Brief History of Drills and Drilling
BEADS: Journal of the Society of Bead Researchers, 1998A microscopic examination of silicone impressions of the perforations of beads, sealstones, and amulets has produced a data base of characteristics that help to define what type of drill was used to make them. This article outlines the various types of drills that have been used from the Palaeolithic period to the present day, and notes what ...

Drilling Holes with the Bow-Drill
Technology and Culture, 1970miliar to most carpenters and joiners in Britain, which appears to corroborate the authors' analysis of the action of the ancient Egyptian stone-boring tool. Fitted preferably with a rosehead countersink bit, it is also used one-handed for countersinking. The rotation is started by tilting the brace, thus making use of the gravity couple similar to the
